I'm another huge fan of the EBR ECM upgrade. Mine is completely stock with only a K&N air filter. Just returned from a long ride and all I can say is wow! Just wow! What a difference! First, the low RPM fueling and driveability is excellent. With the stock ECM, anything below 3.5k RPM is raggedy with a touchy throttle response. Now I can run it down to 2.5k RPM in 2nd gear, pick up the throttle, and the engine powers away smoothly. Second, idle is much more stable. Third, with the stock ECM, the engine had a "sweet spot" of about 4,700-5,000 RPM in top gear, which equates to about 75-78 mph cruise speed. Beyond that and the engine felt slightly rough and frenetic, hence the sweet spot around 77mph. With the EBR ECM, that roughness is gone and replaced with smoothness. I can cruise in a more relaxed manner well above 85 mph and the engine never feels like it's revving too much. This is both good and bad of course because it puts me in danger of getting speeding tickets! LOL! Finally, the engine revs just a little faster and smoother. I haven't tested the extra 500 RPM at the top. This is how the 1125 should run right off the showroom floor! I had done something similar to my 2007 VFR800 (PC III upgrade) and had similar results of smoother running and excellent throttle response. Yet another compelling reason to re-program any motorcycle and purge that EPA mandated tuning! Yeah!!! | ||

You have willfully chosen to thumb your nose at the emission regulations set forth by the great state of California by purchasing a Erik Buell Racing preprogrammed ECM. Did you not read the the following disclaimer: "Use of this ECM is not intended for vehicles operated on the road or otherwise subject to emission control requirements." "In California, this product should not be used on any vehicle that is registered or licensed for use on public roads." Good for you....have fun!!! | ||

LOL! I'm guilty of it...twice! | ||

Wait until you get the Barker or Keda muffler with EBR specific tune, then you have an engine that revs even faster and smoother. | ||
| Rogue_biker |
Dannbuell, I looked into the aftermarket muffler and there were a couple I really liked. Unfortunately, two things stopped me from going for it. I have very good neighbors and I don't want a loud exhaust to taint that relationship. Also, my city has tons of motorcycle cops with LIDAR (we are infamous for them being speed Nazis). I don't want to give them a greater chance of nailing me 1/2 a mile before I even get to their hiding post due to a louder exhaust giving them plenty of warning. Since I commute to work almost daily through the city, this is very important I to me. I'm down to one speeding violation and this will go away next year IF I stay clean! Thus, I passed on aftermarket pipes. The stock one is plenty loud already. | ||

Anyone can tell me how is the fuel consumption compared with the stock ECM? I'm really interested in the EBR ECM, but I'm a bit worried about high consumptions. | ||
| Rogue_biker |
I haven't had a chance to test the fuel consumption. I look at it this way, mileage WILL go down. That's a given. It did on every bike I have ever re-jetted/or re-mapped. However, the reward is so well worth it, it's not even an issue for me. Unless the bike's mileage drops down into the 20's, I don't have a problem with it at all. | ||
| Ros |
Ok I'll wait for your test... I have some friends with the TwinMotorcycles tuned ECM, and they reported high fuel consumption, when the mileage was 210-230 km per tank with the Stock ECM, it drops down to 160-180 with the Twin ECM | ||
| Bob_thompson |
"I look at it this way, mileage WILL go down. That's a given" Actually guys, fuel mileage can be better due to better precise fueling when cruising, but, naturally, when playing and using the engine the way it was intended (a sport bike) it will be less. To prove that out just bring up "instant mileage readout" on the speedo and watch it change from 60 mpg while cruising to 10 when grabbing a handful. But have fun the way it was intended and just watch for the "low fuel" icon. Stay safe, Bob | ||

On startup, do you still get that "bark" when the bike fires or is it less pronounced now with the race ecm? A couple of years ago IIRC, Al from American Sport Bike did exhaust shootouts on a dyno. After each left the dyno, each did a "drive-by" in the parking lot with a microphone at a fixed distance, to demonstrate what each sounded like. I believe the best exhaust/ecm yielded about 136hp at the rear wheel (stock is approx. 122hp), or approx. a 12% hp gain. I wish someone could make an exhaust for the Rotax that, over time, wouldn't make me deaf. | ||

Rogue -- interesting point that you make about quiet pipes giving you a lower profile with the guys who hold the radar guns. Every little bit helps, and IME really loud pipes do tend to annoy them. | ||

I too have decided to pass on the loud exhaust due to similar reasons. Now in order to get noticed from SUVs and trucks trying to kill me I have my fingers all over the horn and brights and I use them almost constantly hehe. - The EBR ECM is being installed very soon on my bike though to get that mid-corner roughness out of the equation. Glad to hear one more rider being satisfied with it. | ||

I've got the EBR ECM with Barker exhaust and i'm still getting around 40-45 mpg (US) when i keep it around ~70mph. When i took my trip from San Diego, CA to Sturgis, SD to Des Moines, IA. I averaged 40 mpg the whole way (2,100 miles in 3 days). From Cali to South Dakota (such a boring route until you get to South Dakota) i was averaging about 70-85 mph the entire time, with a stretch of about 20 miles where i held a constant 120 mph (once again BORING AS HELL). I weighed about 230 lbs with a 30 lbs backpack on me as well. The fueling does go lean when you are just cruising. I had my bike on a dyno and with the sniffer in the pipe, it runs about perfect when you are hard into it gaining speed, but leans out quite a bit when you just cruise. I was told that to get a more even fueling to unplug my O2 sensors. Did that for about 10 miles before i said "screw his advice" cause i was only getting AT BEST 30 mpg when going 65 mph. As soon as i plugged them in, 2 miles later i was back at 45ish. | ||

Keda RT-3 with EBR tune is golden. Can't imagine life without it. | ||
| Rogue_biker |
JrKirk, the EBR ECM is supposed to "ignore" any data from the Oxygen sensors--hence "race only" and illegal in CA. LOL! So plugging or unplugging those O2 sensors should not affect the fuelling. When I installed a PCIII on my VFR800, the O2 sensors connectors were plugged and the kit even came with the plugs!  | ||

Where is everyone getting the EBR ECM at? I can't find it (or I'm just missing it) on the EBR website. Thanks | ||

Take this link: http://www.erikbuellracing.com/store/parts-accesso ries/fuel-injection.html I got mine directly from EBR and shipping to germany was no problem. I hope i'll get my 1125R back in time from maintenance. Can't wait to get the ECM mounted. Cheers | ||

Most of the after market exhausts are still too loud for me, and they do not fill the space under the bike, like the current stock muffler does. To cover up the exhaust, a small spoiler could fill up that area. but the sound would have to be quieter. My vance and hines is too loud now. to start it up at night, I do not feel comfortable of doing anymore. the super trap with the rings is much better at night. sounds like the new ecm is the thing for that motor to use and run right. How would the state know you have that on the bike? In Arizona we have to do emission testing after 4 years old. then every year. Would their sensors notice that you are not within guidlines? | ||
| Usas |
Here in germany we have emission tests every 2 years (called "Abgasuntersuchung", exhaust analysis). Probably our guidelines are stricter than yours. I'm going to exchange the EBR ECM wit the stock one for the test. Then everything's fine. Cheers | ||
| Rogue_biker |
Motorcycles are not required for re-testing in CA. Not yet anyway. I imagine this is the same for AZ? I can't imagine AZ actually makes Arizonians test bikes every two years! | ||

I know the EBR is suppose to ignore the O2 sensor readings, but mine clearly shows that it does pull data from the sensors. On the dyno, at 80 mph with O2 connected, running about 17 ppm from the sniffer. Without the O2 sensors connected, it was getting around 12-13 ppm. Then on the road. O2 sensors disconnected, getting 30. with them connected was getting 45 Maybe mine was just one of the lucky ones that reads the data and gives me good gas mileage. | ||

Here is that link regarding the American Sport Bike exhaust shootout... http://www.americansportbike.com/Exhaust_Shootout. html | ||

I think the 02's still work in closed loop and supply an ego correction factor, but they do not change the AFV. I'm sure they also narrowed the closed loop and the range that the 02's sensors work. Is the engine smoother at cruise with the 02's connected and the ebr ecm, compared to stock ecm? | ||
| Rogue_biker |
Don't know the difference between the o2 connected or not. My 1125R's motor is just smoother with the EBR Race ECM. I notice that smoothness on the highway even more. The best way I can describe it is, both cylinders feel much more balanced in their fueling. Before that it felt "busy" at revs. | ||
| Syonyk |
As far as I understand it, the EBR ECM does listen to the O2 sensors at cruise (as observed by several people), but it does not "learn" from them like the stock ECU does - the AFVs are always locked at 100%. The stock ECU uses the cruise O2 sensor data to adjust the entire fuel map. "Hm... I'm a bit rich at cruise, I need to lean it out. I'll just lean out the entire map." THAT is what the race ECU does not do - according to my understanding. So you get good cruise efficiency with the O2 sensors, and proper fueling in the rest of the range with the non-adjusted map. | ||
| Terrys1980 |
Closed loop is enabled on the EBR ecm so it is making corrections using sensor data. | ||
| Kickstand76 |
not too familiar with the ECU side of the house. is it normally a plug and play kinda deal? been thinking about purchasing it. i have a cbr1000rr can on my bike. dont want to spend $$$ and be sad about negative results. | ||
| D_adams |
 138 hp at the wheel with a target of 13.5:1 or thereabouts. 13% gain. It's even higher hp/tq with the correct ecm. |
